Is there a way to play a system beep on Mac OS?

问题

Is there a way to play a system beep on Mac OS using C++ and Xcode? I understand that I need to use a library. Is there a library that works across both the Mac and Windows platforms?

回答1:

I think you probably want to use NSBeep.

NSBeep

Plays the system beep.

#include <AppKit/AppKit.h>

void NSBeep (void);

This seems to work OK for a command line tool:

#include <AppKit/AppKit.h>
#include <iostream>

using namespace std;

int main(void)
{
    cout << "Hello world !" << endl;
    NSBeep ();
    return 0;
}

$ g++ -Wall -framework AppKit beep.cpp -o beep
$ ./beep

The cross platform way to play a beep is std::cout << "\007";. I had been trying to play it by passing in a char and then decrementing until 7. That didn't work. Explicitly outputting the code did work though.
